Syntax:
bool Imagick::morphology ($morphologyMethod, $iterations, $ImagickKernel, $channel = Imagick::CHANNEL_DEFAULT)Parameters:This function takes four parameters as above and described below:
- $morphologyMethod:this the parameter contains the morphology method to use.
- $iterations:this parameter contains the iteration number to apply the morphology function.
- $ImagickKernel:this parameter contains an ImagickKernel object.
- $channel:This parameter contains Imagick channel constants that provide any channel constant that is valid for channel mode. You can combine multiple channels using bitwise operators. The default is CHANNEL_DEFAULT.
Exceptions:This function will throw ImagickException on error.
The following programs illustrate the Imagick::morphology() functionin PHP:Program 1:
/ / Create a new Imagick object
$imagick
=
new
Imagick (

);
// Create an ImagickKernel object
$kernel
= ImagickKernel::fromBuiltIn (Imagick::KERNEL_DIAMOND,
"2"
);
// Apply morphology function
$imagick
-> morphology (Imagick::MORPHOLOGY_CONVOLVE, 2,
$kernel
);
